SecurityWeek reported on November 17, 2025, that exploitation of XWiki vulnerability CVE-2025-24893 had expanded beyond initial activity to include botnets, cryptocurrency-mining operations, scanners, and custom tools. The flaw involves crafted requests to XWiki’s search endpoint and, according to the report, could allow unauthenticated remote code execution. The report documents activity as of that date; it does not establish the campaign’s status or scale on October 4, 2026.
What is CVE-2025-24893?
CVE-2025-24893 is an XWiki search-function injection vulnerability. SecurityWeek’s November 17, 2025 report says an attacker could send a crafted request to the search endpoint and achieve remote code execution without authenticating.
Unauthenticated access makes the issue particularly consequential: an attacker would not first need a valid XWiki account to attempt the reported attack. Successful remote code execution could let an attacker run code in the context of the affected server. The report does not establish how many instances were compromised or quantify the campaign’s scale.
What exploitation was observed?
SecurityWeek attributed its account of the activity to observations by VulnCheck. The November 17, 2025 report described exploitation expanding to several kinds of activity:
#1 Best Overall
- Botnets
- Cryptocurrency-mining operations
- Scanning activity
- Other custom tools
This is a dated account of observed exploitation, not confirmation that the same activity remains ongoing. SecurityWeek is secondary reporting; its article is not the original XWiki advisory or a direct telemetry feed.
Which XWiki versions are affected?
SecurityWeek listed affected-version boundaries as releases before 15.10.11, 16.4.1, and 16.5.0RC1. Treat these as the boundaries stated in that report, not as a complete branch-by-branch upgrade instruction.
Rank #2
- Comes with secure packaging
- It can be a gift item
- Easy to read text
Confirm the exact fix for the deployed branch in XWiki’s dedicated advisory for CVE-2025-24893 before selecting a target version. XWiki’s security policy explains that publicly known security issues are reported as CVEs and that a dedicated GitHub advisory is created for each fixed issue; that policy does not itself establish this CVE’s technical details or fixed releases.

What should XWiki administrators do?
XWiki’s security guidance recommends keeping instances on a supported version and reviewing monthly security updates regularly. Use the current advisory and supported-release guidance to confirm the remediation that applies to your installation.
Rank #3
- Identify the deployed release and branch. Record the exact XWiki version and check whether the installation is still supported.
- Check the specific CVE advisory. Use XWiki’s advisory for CVE-2025-24893 to identify the fix for that branch; do not infer a target release solely from the broad boundaries in the SecurityWeek report.
- Plan a supported remediation. If a direct upgrade is not possible, XWiki advises evaluating the relevant security fixes and defining a remediation plan, such as an applicable supported minor upgrade or dedicated patch. Validate compatibility and supported status against current XWiki documentation.
- Review monthly security updates. Include XWiki’s update notices in ongoing maintenance so later fixes and guidance are not missed.
If you suspect an instance was compromised, treat remediation and incident investigation as separate needs: applying a fix addresses the vulnerability but does not, by itself, determine whether an attacker previously gained access.
